I was looking for information on the colors of ancient Egyptian ships, and came across these on Amazon. The book by Sintich is more about making models, and might not have much information on the colors of actual ships, but is very handy as it has plans for making scale ship models. Besides, it was only $2.28 with free shipping, so I could not pass on it! The Vinson books just arrived and I have yet to peruse it in depth.
The plan for my Bronze age ships is still as follows: paint them up as historically plausible as possible, and use them for both historical battles and in my fantasy Tékumel battles. No one, except the fine readers of this humble blog, will know the difference...
